Be it known that I, THOMAS B. FERGUSON, a citizen of the United States, residin at Hanford, in the county of. Kings and tate of California, have invented new and useful Improvements in Wheeled Scrapers, of

which the following is a specification.

vThis invention relates to scrapers for excavating and moving dirt, and it has particular reference to an improved wheel sera er, whereby the dirtmay be convenient y moved a considerable distance, if nec-r essary, before dumping.

The invention has for itsobject to produce a simple, durable and eflicient carrying frame, whereby the loaded scraper may be supported without unduly straining any of the parts.

-A further object .of the invention is to support the scraper pivotally in such a manner that it may `be conveniently tilted for the purposeof loading or unloading, as the case may be.

.A further object of the invention is to produce a simple and eiicient wheel scraper wherein the act of inverting or upending the f scraper to discharge the load shall be accomplished by direct draft of the teams, in such a manner as to avoid undue strain on the frame and especially on the scoop supporting members..

-A further object of the invention' is to produce a wheel scraper of a character which will enable the scoop to be convem iently manipulated to place it in position for being dumped andalso in. position for being restored to its initial or 'carrying position by the operator.

With hese and other ends in view which will readily appear as the nature of the in vention is betterunderstood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter full described and particularly pointed out in t e claims.

In the accompanying drawings has been illustrated a sim le and preferred form'bf the invention, it eing, however, understoo that no limitation is necessarily made tothe precise structural details therein exhibited, but that changes, alterations and modifi-A `--cationswithigthe scope of the claims may be resorted to when desired.

In the drawings- Figure 1 is a side elevation of the improved wheel scraper, showing the scoop in its initial or carrying Vposition. Fig. 2 is a top plan view of the same. Fig. 3 is a sectional view taken on the line '3-3 in Fig. 2, showing the scoop tilted to a position for receiving or discharging the load, as the case may be, and with dotted lines showing the scoop further tilted by means of-the unloading lever. Fig. is a sectional view taken on the line 4 4 in Fig. 2, showing the scoop in its discharging pothe team and 'showing also the unloading lever restored to its initial position to enable the lnverting of the scoop to be accomplished. Fig. 5 is a sectional view similar to Fig. 4, but showing the scoop started in Vt-he direction of its initial position by means of the unloading lever.

Corresponding arts in the several figures are denoted by li e characters of reference.

The frame A of the improvedmachine includes rearwardly converging| side members lserving to support between them a box or bearing member 2 for a vertical shaft 3 carrying a yoke 4 which supports a caster wheell or trailer 5. The frame is supported on an axle 6 having transporting wheels 7.

'65 sition to which it is carried by the draft of' Mounted on the parallel forward portions l 84 of the side members ofthe frame forwardly of the converging portions 1, 1 and in rear of the axle, are guides 9 which are preferably strongly constructed of angle iron by bending the same first to an approximate U-shape, and afterward bending 4the limbs to present an` angle at about the point where the guides' are intersected by the side members'S. The lower ends of the slots 1 0 between the limbs of the guides will thus extend downwardly with respect to the side members 8 of the frame,.wh1le the upper ends of the slots willv be distinctly inclined in a forward direction, presenting in# clined planes. The lower ends of the guide -m'embe'rs are connected with the frame by means of truss rods 11, whereby the construction isstrongly reinforced.

12 designates the. scoop which may be con# structed ofsheet metal and of conventional sha e; said scoop being preferably provided wit ,a detachableblade or cut-ting memberU 13. B y varying the width of the cutting member the capacity of the scoop may be varied to some extent. The scoop is provided with trunnions 14vengaging the slots 10 of the guide members, and the parts are so proportioned that when the scoop is in its normal or initial position with its bottom portion in an approximately horizontal position and with the trunnions supported at the lower extremities of the slots 10, the scoop will be supported with its bottom portion clear of the ground, thus enabling the machine to be readily transported whether loaded or unloaded.

Mounted for oscillation on the axle 6 between the side members of the frame is a sleeve 15 having radially 'extending arms 16 which are connected with the sides or end members 17 of the scoop by means of links 18, said links being pivotally connected with the side members 18 near the forward edge of the scoop. Supported on the frame A near the rear ends of the parallel port-ions 8 of the side members of said frame is a rock shaft 19 having radially extending arms 20 which are connected with the sides or end members 17 of the scoop by means of links 21, said links being pivotally connected with the end members 17 in rear of the trunnions 14 and relatively near the upturned rea-r wall 22 of the scoop. y

PivotallyA connected with the trunnions 14 are draft `rods 23 which are extended forwardly and guided through keepers 24 on the front crossbar 25 of the frame. Teams may be attached to the draft rods 23vv by means of eveners, not shown, and the frame is kprovided with a forwardly extending tongue, a portion of which Iis shown at 26. The frame A includes a cross bar 27 which' connects the 'side members of said frame at or near the angles between the forward parallel portions and the rearwardly extending converging -portions of said side members, and supported on said rear lcross bar 27 and on the front cross bar 25 is an arch 28 longitudinally spanning the frame. Fulcrumed on said arch near the rear end thereof is the tilting lever' 29 which is' i equipped with a stop memberl 30 of conventional construction' adapted toengage a segment rack 31 for the purpose of securing the tilting lever. and related parts in adjusted position. The tilting lever is connected by a rod 32 with one arm of a lever 33 fulcrumed on the forward part of the arch,.and the other arm of which is `con` nected by a link 34 with anr arm or crank 35 extending radially from the rocking sleeve 15, which latter may thus be oscillated. Connected directly withthe rock shaft 19 is an armor lever 3G which, for convenience, I term the unloading lever, said lever being of a resilient nature, so as to enable a lug or stud 37 with which it is provided to be placed into or out of engagement with any one of a plurality of apertures 38 in a segment bar 39 which connects the arch member 28 with the rear cross bar 27. The latter cross bar supports a seat -40 for the driver or operator, and the rear 'portion of t-he frame, bounded by the rear cross bar 27 and the converging side members 1, is

provided with liooring 41 for the convenience of the operator. i

The limbs or side members of the guides 9 are connected vtogether and spaced apart at their upper ends by means of bolts 42 and spacing sleeves 43 that serve to obstruct the forward and upward movement of the trunnions 14 when the scoop is being tilted or inverted in the act of unloading.

The parts of the machine are so proportioned and assembled that when the tilting lever is -at the rearward limit of its Vmovement and the unloading 'lever is at the forward limit of its movement, the arms 16 of the rocking sleeve l'and the arms 20 of the rock shaft 19 will be so positioned that the links 1.8, 21 will support the scoop being regulated by the tilting lever. When the machine is drawn in a forward direction by the teams attached to the draft rods 23, the scoop will be quickly loaded, Vand it may then be restored to its initial position by manipulating the tilting lever, after which the load may. be carried any desired distance to the place of deposit. In order to dump the load, the tilting lever is again i manipulated to bring the cutting edge of the scoop into engagement with the gronnd, and the unloading lever is thrown in a rearward direction to oscillate the rock shaft 19, thereby increasing the tilt of the scoop by lifting or elevating the rear portion thereof. If desired, the discharge of the scoop may be delayed by locking the unloading lever at any point between the4 front and rear limits of its movement, in which event the load will be scraped over the suri face of the ground until the dumping point has been reached when, by releasing the un-` loading lever and permitting the same'to swing to the rear limitof its movement, the draft of the teams, exerted directly `on the` trunnions 14 will cause said trunnions to ride upwardly and forwardly over the inclined planes formed by the upper portions Aof the guide Slots 10, until the scoop is practically inverted. During thisportion of the operation, the unloading lever mustl be held by the operator clear -of engagement with the segment bar 39 so that it will not .become locked, this beingnecessary toJ'permit the rock shaft 19 to oscillate forwardly, thereby` permitting the scoop to be prop-- erly inverted to discharge the load and to be sufliciently' lifted above the ground'to clear the material just discharged. The machine A may be returned to the loading point with the scoop inverted, as shown 1n Fi' 4, or

the scoop maybe previously restore vto initial posi ion. This is .accomplished by r'st the tilting lever to its initial position, thus carrying the cutting edge of the scoop forward and supporting it clear of the ground and then swinging the unloading lever to the rearward limit of its movement frame, a scoop having trunnions and releasing it to permit it to return to its initial position. By -this movement of the unloading lever, the rear portion of the scoop will be carried through an arc, where by the scoop is restored to its normal initial position, this last operation being greatly aided by the gravity of the scoop.` l

As will'be seen from the foregoing description, the improved scraper is simple in construction and very easily manipulated, the several operations being performed 1n a natural andlgradual manner, withoutv the necessity of any great exertion on-the part of the operator; the unloading operation especially being'l performed by the :draft of the team.l The machine has in practice been found to be thoroughly efficient for the pur- Wheel `supported frame, rocking members mounted on said frame and having radially extending arms, slotted guides fixed on .the engaging and ridinginthe slotted guides, linkscon .necting the front end of the scoop with the ,arms of one rocking member, and links connecting the rear end of the scoop with the arms of lanother rocking'member; in combination-with draft members connected with the trunnions of the scoop to assist in moving the latter along the slotted guides.
